Micro Abstract:
The objective of this work is to study the fiber kinking and subsequent fiber/matrix debonding in FRP composites under unidirectional compressive loading. In the micro-scale, geometrically nonlinear cohesive elements are used in order to model the shear failure of the matrix material at its interface with the fibers which results in initiation and evolution of local splitting between fiber and matrix and drives the rotation of fibers up to kink band formation.
